Chapter 7. Network Configuration
Save
Saves the Networks and Computers configuration to the preliminary configuration.
Cancel
Clears and resets all fields in new rows and reset changes in old rows.
Interface (Network Interface 1 and 2)
There is a menu selection for each network interface (Network Interface 1 and 2) on the Telecommuting Module.
Select a page to make configuration for that interface. There is also a page where configuration for all interfaces can
be viewed and changed.
Here, you set the interface name, whether the interface is on or off, the IP address, alias, and static routing.
For each interface, go to Directly Connected Networks and state the IP address of the Telecommuting Module and
the size of the network connected to this interface.
General
Physical device name
This tells the physical device name of the network interface. The physical interface eth0 corresponds to Network
Interface 1, and eth1 corresponds to Network Interface 2.
Status
Specify if this network interface is On or Off. If the interface is off, all configuration on this page is ignored, and
the Telecommuting Module will behave as if this interface wasn’t present (except when used for failover).
If the interface should be used for failover, you should select Off. In this case, it won’t be available for other traffic
than the synchronizing within the failover team. Read more about failover in chapter 12, Failover.
Interface name
The network Interface name is only used internally in the Telecommuting Module, e. g. when configuring
Networks and Computers.
Directly Connected Networks
The Telecommuting Module must have an IP address on every network to which it is directly connected. This
applies to all networks on the same physical network to which this interface is connected.
Note that the interface which should receive traffic from the outside must have a public IP address (no NAT),
regardless of which Telecommuting Module Type was selected. For a DMZ or DMZ/LAN type, this means that
the interface connected to the DMZ of the firewall must have a public IP address.
